M16-GAP-00222 Status

status: done task: armature.collection_assign operator LOCAL_EXACT slice updated: 2026-08-22 America/New_York

scope:

• The minimal fixture contains one armature bone assigned to WebGapArmatureCollectionAssignSource and an empty target collection.
• Desktop runs ARMATURE_OT_collection_assign(name=target) with poll=true and FINISHED, adding the selected bone to the target while preserving its source membership through save/reopen.
• The existing Main reader exposes both collection member ID lists; no new reader field, data-block, editor, or browser behavior was added.

evidence:

• The generator, desktop checker, npm comparator, direct comparator, and task-context checks passed. Repeated checker runs recognize the persisted assignment and remain idempotent.
• WASM/Main observes the same assigned bone ID in both collections, preserves it across save/reopen, and rejects malformed Blend input without Main mutation.
• Chromium-only policy was preserved; no Firefox/WebKit run was made.
